Rancilio Replacement Burrs for Rocky and MD40 Grinders and Screws (6)

These are genuine Rancilio replacement grinding burrs for all models of the Rancilio Rocky Grinder as well as the commercial Rancilio MD40 Grinder. If an errant rock or other foreign object has damaged your current burrs, or you have just ground hundreds of pounds of coffee, you will need to replace both burrs using this O.E.M. set of 2 from Rancilio. These Rancilio burrs measure 50 mm in diameter. They are very simple to replace and will give you the opportunity to give the grinding chamber a thorough cleaning at the same time. It is recommended to replace the screws that secure the burrs to their respective carriers when you perform this task (6 total, sold separately). Rancilio Part Number: 69000032 PLEASE NOTE: It is common for burrs to have "spots” of oxidization from exposure to air; this does not mean that the burrs are used or inferior in quality in any way.
